A capillary tube with a bore diameter of 0.5 mm is dipped upright in a liquid having surface tension 0.03 N. m^-1 . The specific gravity of the liquid is 0.8 and the liquid wets the surface of the tube completely. Up to what height will the liquid rise in the tube?

A spherical liquid drop is placed on a horizontal plane. A small disturbance causes the volume of the drop to oscillate. The time period of oscillation (T) of the liquid drop depends on radius (r ) of the drop density ( rho ) and surface tension (s) of the liquid. Which among the following will we be a possible expression for T (where k is a dimensionless constant )?

It two physical quantities a and b are related by the equation a = kb where k is dimensionless constant, then the principle of dimensional homogeneity demands that a and b have the same dimension. However the proportionality constant k cannot be determined by dimensional analysis only. It may at most be written that a prop b if a and b are of the same dimension. Time period (T) of oscillation of a liquid drop depends on its radius r the density rho and the surface tension sigma of the liquid. Then T is proportional to
